Re: Back to Automatic overdrives for a second...
If your car has an automatic gearbox then it almost certainly has a
transmission oil cooler fitted as part of the coolant radiator. You could
fit an extra one if you want. However it would need to be fitted in series
with the one in the radiator. If you just replace the solenoid I am sure
that it will work OK again.
